Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a container for disposing of used syringe needles.

Prior art and its problems Traditionally, used needles were removed from syringes by hand and disposed of in a waste container. However, if the blood adhering to the needle contains pathogens such as hepatitis B or AIDS, if you accidentally poke your skin with the tip of the needle while removing the needle and discarding it in a container, the blood that has adhered to the needle may be present. There was a risk that pathogens such as hepatitis B and AIDS in the blood could enter the body and cause infection with these diseases.

The object of this invention is to provide a needle disposal container that allows the needle to be removed from the syringe without being touched by hand and can be disposed of into the disposal container.

Means for Solving the Problems In the needle disposal container according to this invention, at least a portion of the lid fixed to the container body is formed of an elastic sheet, and a needle insertion hole is formed in the elastic sheet. , four slits are formed radially at equal intervals in the circumferential direction on the peripheral edge of the injection needle insertion hole, and a tongue-like piece for removing the injection needle is formed between adjacent slits. .

In the above, the elastic sheet is
Those made of plastic such as polyethylene, rubber, etc. are used. Also, the sheet is 0.5
The thickness is preferably about 2 mm. The lid is
The entire cover may be made of an elastic sheet, or the sheet may be fixed to the cover so as to close a hole drilled in the cover.

Function When removing a used needle from a syringe using the needle disposal container of this invention, first insert the needle into the needle insertion hole and push the syringe downward. Then, the tongue-like pieces between adjacent slits in the elastic sheet are deformed. When the needle enters the container, the tongue tends to return to its original shape due to its own elasticity, and is inserted between the lower end of the syringe barrel and the flange of the syringe needle joint, or is pressed against the joint. If the syringe barrel is pulled upward in this state, the flange will be pushed downward by the tongue-like piece inserted between the lower end of the syringe barrel and the flange at the junction of the syringe needle, or the junction will be pressed against the junction. The joint part is pushed downward by the tongue-shaped piece, and the joint part comes out of the small cylindrical part of the syringe barrel, and the syringe needle comes off and falls. Then, it is housed in a container. The needle is thus removed from the syringe. When the container is full of used needles, discard the entire container.

In addition, since the elastic sheet has a needle insertion hole formed therein, the needle can be removed as described above by inserting the tip of the needle into the insertion hole and pushing down. can. Therefore, the injection needle can be removed reliably. If no injection needle insertion hole is formed and only a slit is present, there is a risk that the injection needle will not be able to be removed if the tip of the injection needle hits the tongue-shaped piece between adjacent slits.

In addition, four slits are formed radially at equal intervals in the circumferential direction on the peripheral edge of the injection needle insertion hole, and a tongue-shaped piece for removing the injection needle is formed between adjacent slits. The width of the tip of the shaped piece in the circumferential direction can be made relatively large. Therefore, pressing down the flange by the tongue inserted between the lower end of the syringe barrel and the flange of the joint of the syringe needle, or pressing down the joint by the tongue pressed against the joint requires a large force. It will be held in
The injection needle can be removed reliably. If the number of slits is greater than this, the circumferential width of the tongue becomes narrower and there is insufficient force to push down the flange or joint, making it impossible to remove the needle.

Embodiments Hereinafter, embodiments of this invention will be described with reference to the drawings.

In FIGS. 1 and 2, a needle disposal container 1 includes a cylindrical container body 2 made of metal, plastic, etc., and a plastic sheet lid that is bonded and fixed to the upper end of the container body 2 to close the upper opening. 3 and more. The lid 3 is integrally provided with a circular rib 4 that projects downward and is concentric with the periphery of the lid 3 when viewed from above. In addition, a hypodermic needle insertion hole 21 is formed in the center of the lid 3.
Four slits 20 are radially formed at equal intervals in the circumferential direction on the peripheral edge of the slit 1 . The tongue-shaped piece between adjacent slits 20 is indicated by 6.

Such a needle disposal container 1 is used to remove a needle from a syringe without touching it by hand.

The syringe 10 includes a syringe barrel 11 and an injection needle 13 attached to a small cylindrical portion 12 at the tip of the syringe barrel 11. The injection needle 13 has a joint part 14 fitted over the small cylindrical part 12 of the syringe barrel 11, and a joint part 14.
The needle body 15 is fixed to the needle body 15. Joint part 14
A flange 16 is provided at the end of the cylindrical portion 12 that is fitted over the small cylindrical portion 12 .

Next, a method for removing the used injection needle 13 from the syringe 10 using the injection needle disposal container 1 will be explained with reference to FIGS. 3 to 5. First, the needle 13 is inserted into the needle insertion hole 21 and the syringe 10 is pushed down. Then, each tongue-like piece 6 bends downward as shown in FIG.
6 enters the container 1, each tongue-like piece 6 tries to restore its original shape due to its own elasticity and enters between the lower end of the syringe barrel 11 and the flange 16 (see FIG. 4). If the syringe barrel 11 is pulled upward in this state, the flange 16 is pushed downward by the tongue 6 and the joint 1
4 comes off from the small cylindrical portion 12, and the injection needle 13 comes off and falls (see FIG. 5). Then, it is housed in the container 1. In this way, from the syringe 10 to the needle 1
3 is removed. When the container 1 is full of used injection needles 13, the entire container 1 is discarded.

In the above embodiment, the entire lid 3 is made of an elastic sheet, but it is not limited to this. A hole is made in the lid made of another material, and an elastic sheet is used to close the hole. A sheet having a slit may be fixed to the lid, and a slit may be formed in this sheet.

Effects of the Invention According to the syringe needle disposal container of this invention, as described above, the syringe needle can be removed from the syringe without being touched by hand, and can be disposed of into the disposal container. Therefore, when removing a used syringe needle and disposing of it in a container, the tip of the needle does not accidentally poke the skin, and the hepatitis B in the blood that was attached to the needle can be removed.
There is no risk of pathogens such as AIDS entering the body and infecting these diseases. Furthermore, the injection needle can be removed reliably.
